A fire shelter is a safety device of last resort used by wildland firefighters when trapped by wildfires. While such a shelter cannot withstand sustained contact with flames, it can protect a firefighter's life in a short-lived grass fire. Furthermore, it is designed to reflect radiant heat, protect against convective heat, and trap breathable air — most firefighters' deaths are from inhaling hot gases — so that firefighters can survive in non-burning areas surrounded by intense fire for more than an hour.{{Cite web|url=http://www.fs.fed.us/rm/pubs_int/int_gtr299/|title=Mann Gulch Fire: A Race That Couldn't Be Won (archived 08-13.2009)|publisher=United States Department of Agriculture, Forest Service|date=1997-01-13|access-date=2017-06-27|archive-date=2009-08-13|archive-url=https://web.archive.org/web/20090813122911/http://www.fs.fed.us/rm/pubs_int/int_gtr299/|url-status=bot: unknown}}

The first known use of a fire shelter was in 1804, when a boy was saved from a prairie fire when his mother covered him with a fresh bison hide. William Clark noted in his journal that the fire did not burn the grass around the boy.{{cite journal|date=Summer 2000|title=First Peoples First in Fire Shelter Use|journal=Fire Management Today|publisher=U.S. Department of Agriculture, Forest Service|location=Washington, DC|volume=60|issue=3|pages=39}} In the United States fire shelters began being used by wildland firefighters during the late 1960s and have proven extremely effective.
